The contest on Mount Carmel was to determine wether

The contest on Mount Carmel was to determine whether God or Baal was to be worshipped in Israel. In 1 Kings 18, Elijah challenged the prophets of Baal to a contest to determine which deity was the true God. The prophets of Baal built an altar and called on their god to send down fire to consume their sacrifice, but nothing happened. Elijah, on the other hand, built an altar, put his sacrifice on it, and called on the God of Israel to send down fire, which He did. This miracle demonstrated that the God of Israel was the true God and that He alone was to be worshipped in Israel. Therefore, the contest on Mount Carmel was to determine whether God or Baal was to be worshipped in Israel.
